I wonder if somebody can help me identify the fixture in the attached picture? It is in the ceiling above the aft berth.
Thank you
Its a standard access panel (screw style). Take look at at what is just above it outside. It could be access to the underside of a winch and it's bolts or something like that.
Stick your fingers into the finger cut-outs and unscrew it.
It's a Beckson threaded deck plate. On my boat it provides access to the fasteners attaching the starboard self tailing winch to the coaming.
I was scared to open it :D
I agree, that's where I accessed the starboard winch nuts when replacing my winches.
Sophie : Please identify the production year of your C34!! All C34s are not exactly alike.
It could be a Beckson screw-in port access to cover the intake to the solar vent?
I installed Beckson deck plates like that on that solar vent in the aft cabin and on the inside of the 2 dorade vents in the main salon. When the WX got cold and I needed to keep in the heat, I'd screw in the caps. Otherwise the caps were out and stored!!
